I am running an emulation of an FFT using aocl 19.1.0.240 with s10_gh1e1_4Dx2 board.
But when I tried comparing the radix-4 butterfly with (#pragma unroll before the for loop) and without loop unrolling, there is no difference in their processing time. Can anyone help me with this? Thank you so much.

Hi,
I am unsure what the causes might be, we do have a tutorial on usage of loop unroll below:
You could try the example, and if the problem persists let me know.
